**Table Analysis and Mean Estimation** There are 212 students at a local college taking an Introduction to Statistics course. Below are the final exam scores of 30 randomly selected students. The task is to estimate the mean score for all students in the course, rounding the answer to the nearest whole number. **Final Exam Scores:** | 97 | 54 | 78 | 75 | 86 | 80 | |----|----|----|----|----|----| | 94 | 96 | 68 | 62 | 76 | 72 | | 72 | 89 | 73 | 82 | 81 | 57 | | 92 | 77 | 88 | 52 | 80 | 58 | | 65 | 81 | 85 | 59 | 64 | 90 | The table consists of 5 rows and 6 columns, featuring integers ranging from 52 to 100. **Options for the estimated mean score:** - The estimated mean score is 77. - The estimated mean score is 74. - The estimated mean score is 78. - The estimated mean score is 76. To find the estimated mean, calculate the sum of all scores and divide by the number of scores. Then, round the result to the nearest whole number.
